As shown inthese drawings, 8 indicates a vehicle spring of any ordinary or prelierred form of construction to which our device may be applied. A bracket 9 is made to fit over the lower portion of the spring and has a projecting in 10 adapted to engage with one end of t e spring 11. The bracket is completed by, or engages with a clip 12which is held in position by means of nuts 13. This clip 12 also has a nrojecting pin or axle 14 on which is mounted a sleeve 15 having a projecting arm 16 provided with means, preferably a hook, at its outer end for engagement with a chain or connecting device 17. The sleeve 15 is secured to the inner end of the spring 11 and for this purpose is preferably made square to engage with a square hole formed at the center of the spring, as shown particularly in Fig. 3. T he spring is proforably made in the form of aspiral, making What is commonly known as a clock spring. The opposite end of the chain 17 is connected the body oi the vehicle in gain. ibvegt'reugli women, or ent te.

Then, as the vehic e springs expand and tend to throw the body upwardly, the action will be against the tension of the spring 11, which tension increases as the arm 16 moves up, and thereby prevents the undue upward movement of the vehicle springs and tends to reduce or absorb the shock.

A slightly difieren't arrangement of the device is shown in Figs. 4 to 6, inclusive, in which 19 represents a hinged bracket ada ited to be clamped to the axle 20 of the vehicle so that the projecting arms 21 will be held rigidly in any desired position. A pin or rivet 22, extending between the arms 21, adjacent to-their inner ends, serves to hold one end of the spring 23 which has its other or inner end secured to a square shaft 24, as indicated in Fig. 5. This shaft engages with square holes in the inner ends of the lever arms 25 -25 these arms having rounded projections or bearings 26 which engage with round holes in the ends of the arms 21, as indicated in Fig.6. A cross-bar or pin 27, at the outer ends of the arms 25, serves as a means of connection for the con necting chain 28 or other equivalent con nection which has its opposite end connected at the upper part of the vehicle spring or to the body of the vehicle. The 0 eration of this form of device substantial y the same as that hereinbefore described.

The above descri tion and the accompanying drawings i lustrate the essential wish to be limited to the exact coi'istruction spring having one end secured to said bracket, a bearing on said bracket, e' sleeve mounted on said bearing and connected with the opposite endof said spring, an arm projecting from said sleeve, :1. chain connected to the outer end of said min, and 11 hook secured to the top portion of said vehicle spring and connected with the opposite end of said chain. c
